SPECIFICATION forming part of Letters Patent No. 476,976, dated June 14,1892.

Application filed January 28, 1892I Serial No. 419,505. (No model.)

To all whom it may concern:

Be it known that we, GEORGE W. BROWN and OLOF A. JOHNSON, citizens ofthe United States, residing at Galesburg, in the county of Knox andState of Illinois, have invented certain new and useful Improvements inCultivators, of which the following is a specification.

Our invention relates to parallel or tongueless cultivators of thatclass or type in which runners are used as the supporting parts of thetruck to which the plow-gangs are hinged and after and by which they aredragged and in which the supporting-runners are pivotally connected withthe other parts of the truck, so that the runners may be heldsubstantially in the line of draft and by the draft or some constructionof the truckframe when either runner is advanced or receded withreference to the other; and our present improvements have for theirobject to provide for use a cultivator of the type referred to whichshall be efficient in its operation, economic of manufacture, strong,durable, and readily and easily managed in use in the field by anyperson at all skilled in such work.

To this main end and object our invention consists in mechanismsembodying novel structural peculiarities and in combinations of partswhich are hereinafter more fully described, and specifically pointed outin the claims hereto appended.

In the accompanying drawings all our improvements are shown as embodiedin the best way now known to us and as carried into effect in thatprecise form of cultivator in which we have so far practiced it, thoughas to some or all of the several novel structural features the form ofthe parts may be more or less modified.

The preferred construction of parts and combinations referred to areillustrated in the accompanying drawings, in which Figure 1 is aperspective of the cultivator made and used by us; Fig. 2, a sideelevation; Fig. 3, a top plan; Fig. 4:, a perspective of one side frame;Fig. 5, a rear elevation of the side frames connected by the arch,showing one side frame partly broken away to more clearly show its hingeto the arch; Fig. 6, a rear elevation of a side frame and sectionalelevation of the forward end of a plow-gang; Fig. 7, a side elevation ofone of the support ing-runners; Fig. 8, a top plan of a side frame; Fig.9, a top plan of a runner, side frame, and brace as connected with eachother.

The several reference-letters hereinafter used are each used in thedifferent figures of the drawings to designate the same part.

Each side frame A is formed of two parallel bars a, united at or nearone end bya vertical bar a, which is preferably integral therewith. Thebars a have ordinary coincident holes a for the pin a which passesthrough them and through a block a, that swings horizontally on said pinand to which the plow-beam plates Z) are hinged by a bolt 11, by whichordinary means the plow-gangs B can be adjusted at different distancesapart and be swung laterally and vertically in the ordinary manner whenin use. The vertical ends 0' of the yoke or arch O are rounded andjournaled or pivoted in the coincident holes a in the inner ends of thebars a, as shown particularly at Fig. 5. A shoulder or collar 0 on eacharch end 0 above the upper bar a and a pin 0 through each end 0 belowthe lower bar a serve to maintain the connections between the arch oryoke and the side frames A, while permitting said frames to swing orsway laterally on the ends 0' of the arch as journals.

The supporting-runners D are each formed of a sled-runner-shaped part d,with curved braces d extending upwardly to form supports for therectangular part 61 the upper and lower sides of which contain recesses(1 The outer ends a of the arms a are fitted in the recesses 61 in therunner-frames, the upper arm a in the upper recess, and the lower arm ain the lower recess, and are held in such fixed position by a bolt d Theouter end of each arm a has also shoulders a", which rest against theinner side of the runner-frame and in an evident manner aid in makingthe connection between the runners and frames A fixed, rigid, andsecure, while at the same time easily separable by simply removing thebolts d The forward ends of the runners D are each perforated for thereception of a ring e, to which a draft-animal may be attached,

and each of these rings is interlocked with an eye on the forward end ofa brace-rod f, which diverges from the runner as it extends rearwardlyof the cultivator and is fixed to the vertical end of the arch or yoke Oby encircling it. These rods f serve as braces to further strengthen theattachment of the runners to the side frames A and to maintain therunners and side frames at substantially right angles to each other,whereby, the runner when in use in cultivating plants being, as in allparallel cultivators, in line with the draft, the side frames A will beheld thereby at right angles to said line of draft or forward movementof the cultivator not only when the arch or yoke C is at right angleswith the line of draft, as shown by full lines at Fig.3, but also whenby the advance of either draft-animal relatively to its fellowdraft-animal or from other causes one side frame and runner are advancedrelatively to the other side frame and runner and the arch or yoke O ismoved into a position oblique to the line of draft, as shown by dottedlines at same figure, which dotted lines show one such oblique positionof the arch or yoke, with the runners in the line of draft and the sideframes each at right angles with the runner to which it is affixed.

The plow-gangs are suspended with their shovels above the ground onhooks g at the rear ends of rods G, the other or forward ends of whichrods are fixed by bolts 9 one to the rear side of each rectangular partd of a runner, and the lower parts of the runners extend to suchdistances in rear of the couplings of the plow-gangs to the side framesA that they will support the plow-gangs when so elevated without tiltingor falling back- Wardly.

The combination of the runners D and, side frames A, rigidly connectedwith each other, and said side frames pivotally connected at their innerends with the vertical ends of the arch or yoke 0 produces a simple,cheap, strong, durable, and in operation a very effective truck-framefor a cultivator of the class shown, and in which when either runner isturned shortly it will swing on the pivot at the end of its side framenext to the arch or yoke O, and hence be drawn in, so turning to acertain extent lengthwise of itself, and not be dragged around sidewiseof itself to destroy small plants in turning, as is the case when thepivotal point on which the runner turns laterally or horizontally is atthe runner, and in which the liability of the runners to swing oroscillate laterally, and thus the swinging or swaying of the runners atevery obstruction and at every slight sway of either draft-animal isreduced to a minimum, as when the pivotal point of the run- 1. Incombination, in a parallel cultivator,

side frames to which the cultivator-gangs are hinged or journaled,runners rigidly fixed one to the outer end of each side frame to supportsaid frame and swing or sway with it, and an arch or yoke the verticalends of which are pivotally connected with the inner ends of the sideframes, substantially as described.

2. In combination, in a parallel cultivator,

side frames A, yoke or arch O, pivotally c011- nected with the innerends of the side frames, and runners D, rigidly aifixed to the outerends of said side frames, substantially as de scribed.

3. In combination, the arch or yoke C, having vertical journal ends 0',the side frames A, having parallel bars Ct, with coincident holes a inwhich the ends of the yoke or arch are journaled, the coincident holes afor the pin a to which the plow-gangs are hinged or Journaled, the barsa, connecting the outer ends of the bars a, the runners D, constructedsubstantially as described and having a rectangular upper portion d withrecesses d in its upper and lower sides, which receive the ends of thebars a, the belt 01 and the shoulders a on the bars a, substantially asdescribed, and for the purpose specified.

4:. In combination, the arch or yoke and the side frames having theirinner ends journaled to said yoke and their outer ends fixed to runnersD by a bolt d substantially as described.

5. The combination, substantially as hereinbefore set forth, in aparallel cultivator, of

an arch or yoke and side frames pivotally connected at their inner endswith said yoke and at their outer ends rigidly connected with runnersfrom the forward ends of each of which a brace-rod extends to theVertical part of said arch or yoke to stay and brace the runner and sideframe each with the other.

In testimony whereof We affix our signatures in presence of twowitnesses.
